Well the size of the jar is a perfect size. It allows enough room to add several things to my smoothies. The motor is strong , I suspect that this blender is the strongest one I've had. Been a cheerleader/fan of the Hamilton Beach blenders for over 30 years. The one thing I am not thrilled with is that the blending jar is plastic. Not a fan of plastic, as it gets cloudy after time and can crack and become useless. You MUST hold the lid down or it will come off while blending, and I'm sure would end up on everything. I like this very much and will treat the jar gently.
